COTTON CLEANER.

I Application filed September To all whom it may concern:

Be it known that I, LUTHER M. KINARD, a citizen of the United States, residing at Royse City, in the county of Rockwall and State of Texas, have invented certain new and useful Improvements in Cotton Cleaners, of which the following is a specification.

This invention relates to pneumatic cotton cleaners, and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a seed cotton cleaner of durable structure, in which the cotton is drawn from a wagon into the body of the casing of the cleaner and is subjected to the action of the rotary breaker and at the same time removing fine particles of dirt from the cotton. From the breaker the cotton passes into the bottom of the casing and is subjected to the action of several series of spiked rollers and at the same time is subject to suction draft, whereby the particles of hulls are broken from the bolls and are removed from the body of the casing.

In the drawing, the figure is a longitudinal sectional view of the cotton cleaning apparatus.

The cotton cleaning apparatus comprises the casing 1 having an upper chamber 2, and a lower chamber 3. Concaved screens 4 are supported by the floors of the chambers 2 and 3. The cylindrical breakers 5 are journaled for rotation in the chambers and are provided with outstanding spikes 6, openings 7 being provided at the end of each chamber and suction pipes 8 are connected with the opposite ends of the said chambers and at points below the screens 4:. The pipes 8 are. also connected with a suction drum 9. A hood 10 is disposed over the top of the casing 1 and is provided at a point between its ends with a breaker chamber 11. A breaker 12 is journaled for rotation in the chamber 11. A screen 13 is disposed over the chamber 11 and the same extends through the intake end of the hood l0 and is disposed above the upper side of the intake pipe 14. A suction pipe 1 5 is connected with the opposite end of the hood 10.

In operation, the pipe 14 is inserted in a wagon body or other receptacle containing the cotton, and suction draft is created 16, 1924. Serial No. 738,083.

- through the pipe 15 and the drum 9. Thus the cotton is drawn through the pipe 14: under the hood 10 and under the screen 13. The suction created by the pipe 15 draws the dust from the cotton through the openings in the screen 13 and this dust is carried out through the said pipe 15. At the same time, the cotton bolls enter the chamber 11 and are subjected to the action of the breaker 12, whereby the hulls are fractured and the cotton and the partially separated hulls fall into the upper chamber 2 of the casing 1.

The material that enters the chamber 2 is acted upon by the cylinders 5 and the spikes 6, and the cotton lint is worked by the action of the said cylinder and spikes toward the opening 16 at one end of the chamber 2 and the particles of hulls and the particles of dirt pass through the openings in the screen 4E above the bottom of the chamber 2 and are drawn through the pipe section 8, into the drum 9.

At the same time, suction draft is created through the lower pipe 8 and some of the material is drawn from the upper chamber 2 through opening 16 into the lower chamber 3 where it is subjected to the action of the cylinders 5 in the lower chamber and the cotton lint is worked toward the opening 17, in the lower chamber 3, and the particles of dirt are drawn from the lower chamber through the lower pipe section 8 and into the drum 9.

Thus, it will be seen that the cotton is cleaned by using clean air, as the air which is withdrawn from the chambers 2 and 3 through the pipe 8 enters the chambers 2 and 3 through the openings 7 and the air which is drawn through the pipe 15 enters the cleaner through the pipe 14 with the cotton, but does not enter either of the chambers 2 and 3.

Having thus described the invention, what is claimed is:

A cotton cleaner comprising a casing having interiorly located spaced compartments which communicate with each other at one end of the casing, each compartment being provided at its end with an opening, screens spaced above the floors of the compartments, exhaust pipes communicating with r the interior of the compartments at points below the screens, heaters journaled for r0- tation above the screens, a hood disposed over the casing and provided at a portion be tween its ends With a breaker chamber which communicates with one compartment, a breaker journaled for rotation in the breaker chamber, a screen disposed in the hood and extending over the breaker chain-- ier, an intake pipe connected under one end of the hood and an air exhaust pipe oon- 10 neoted with the opposite ends of the hood. In testimony whereof I afiix my signature.
